The major functions of the excretory system is to remove wastes from the body and prevent pathogens from entering and exiting the body.
To rid the body of waste products like urine and other harmful, acidic components.

The major function of the excretory system is to remove waste and toxins from the body. Each works in a different way to filter.
Urea is the main nitrogenous waste in the excretory system. It is a non-toxic option for getting rid of the byproducts of protein metabolism. In addition, it functions within …the nephron of the kidney to modify the concentration of urine under the influence of antidiuretic hormone.
You have two bean shaped stuctures placed in postrior abdominal wall. They are retroperitoneal. Right kidney is slightly lower than left due to liver on right side. It is 3*2*…1 inches in dimentions. On cross section you can see the cortex and medula. You have minor and major calices. Microscopically, you have one million of nephrons in each kidney. There you have glomerulus, descending and ascending loops of henley and collecting ducts. From cortex to medula, you have higher concentration of salt. for this lot of energy is spent. Brain is the organ, which is most vulnerable to excess of toxic products of metabolism. That is serum urea. To excreate urea, kidney filters out 180 liters of fluid each day and more than 178 liters are reabsorbed. That is the main function of kidney. It also regulates the water balance of body. It maintains the pH balance of body. It maintains the salt balance of the body as well. It has endocrines functions as well. By secreating 'Renin' hormone, it activates the renin angiotensin aldesteron mechanism to increase the blood pressure if challenged. It also secretes hormone erythropoitin to stimulate the production of red blood cells. It also converts the 25 hydroxy cholecalciferol to 1,25 cholecalciferol or calcitriol.
A bladder acts a storage tank for urine. It remains there until you are ready to release it. The gall bladder has a similar function.
From both kidney, you have ureters going to the urinary bladder. Urine is produced drop by drop and collected in the urinary bladder. This urine is transferred to the bladder …by pair of ureters, one each, from both kidney. This long passage help to prevent the frequent bladder infection from ascending to kidney.
